Navitas House Bioswale
About the Program
The DTE Energy Downtown Detroit Headquarters Complex is adjacent to the Detroit River between Lake St. Clair and Lake Erie. It includes the Navitas House Bioswale project, which is a 6000 square foot area landscaped area comprised of species including over 30 species of native plants, including drought-tolerant species. The habitat objective of the project is to attract beneficial pollinators, such as bees and Monarch butterflies and birds, while simultaneously providing both critical stormwater runoff treatment and retention, and an attractive landscaped green space in the urban environment for the enjoyment and education of employees and visitors as part of DTE’s “Energize Detroit” initiative.
Practices and Impacts
- The team uses this site for educational purposes to teach about rain gardens and storm water is collected and filtered to help prevent flooding.
- Through selective herbicide treatments and weeding, the team works to eradicate invasive species (e.g. wild carrot and Canada thistle). Presence of 32 species of native plants in 2020 indicates diversity.
- The site is managed by planting native vegetation to attract pollinators. Many species of birds and butterflies have been observed using the site during the growing season.
- The drainage pipe from the roof was relocated to correct erosion issues and redirect flow to the middle of the bioswale.
- Evidence of pollinating numerous species of insects was acquired to demonstrate success at attracting desirable pollinating species; birds are also noted as present.
